Lutieri,

	Vamos partir para o lado onde pode ser algo no processo de compilacao 
do squid.
	Lembro que na epoca do squid 2.6.2 esse cara naum funcionava com ipfw 
(proxy transparente) e nem o coss andava... Entao tive que apelar...
	Alem das configuracoes normais, eu compilei ele com o gcc-4.0 na epoca 
e com as seguintes confs:
	make SQUID_CONFIGURE_ARGS="--enable-dlmalloc 
--enable-storeio=diskd,ufs,coss,aufs,null 
--enable-removal-policies=lru,heap --enable-coss-aio-ops --with-pthreads 
--with-aio"

	Será que se compilassemos este squid com gcc-4.2 (de agosto de 2007) e 
verificassemos se naum tem algumas opções que possamos passar no braco 
(como fiz acima) talvez naum resolveria o problema ?
	Ou talvez separar do squid os processos de consulta a dns, usando o 
dns_helper ?

	Apenas algumas ideias, pois pelo informacoes que voce postou me parece 
que realmente o sistema (FreeBSD 6-Stable) tah legal agora, restando 
apenas o tal do squid a ser analisado/retrabalhado!!!!


Abraços,
